Product description

BNW-W series circular open-close outdoor waterproof current transformer ,the biggest feature of this series of products is the waterproof function ,which can be used outdoors. The cut end face of the magnetic core is sealed with a silicone ring ,which can effectively prevent rainwater from infiltrating; The shell adopts an integrated molding process of ultrasonic fusion welding ,and the transformer winding structure is cast with epoxy resin and the secondary side the lead wire is sheathed to prevent rainwater from infiltrating the transformer body. The waterproof level can reach IP66.

Product characteristic

Open and close structure ,easy to install on site and easy to operate .Quick and easy installation or removal without disconnecting the primary cable under test ,effective for safe and easy current testing.

Wide quantity limit and strong anti-saturation ability .Input current range 0~600A

Flame retardant properties ：According to UL94-V0；

Protection class：IP66
